5.5HP 53cc Twin Cylinder Gas Engine (RU Warehouse)

The new 53cc twin boxer engine has two horizontally opposed 26.5cc cylinders providing 5.5hp of low vibration power.
The two cylinders dynamically balance the engine, making it a smoother running and more reliable idling engine than a single bore motor of the same size. Having double the spark this engine not only idles better, it also has quicker throttle response and a much nicer exhaust note!

Take note of the CNC machined crankcase and finely cast cylinder head, this is a quality motor!

• CDI Electronic ignition with auto advance
